Redis is an in-memory database that persists on disk. The data model is key-value, but many different kind of values are supported: Strings, Lists, Sets, Sorted Sets, Hashes
Starting two instances on different servers. Both are initially set as master with nothing connecting them, and they run fine. When I set one instance to be slave of the other, the master crashes. I have run the memory test and confirmed that it's not a bad memory issue. This is the log from the master:
[10712] 21 Jun 15:22:37.288 # Server started, Redis version 2.8.2104
